I seem to have a degenerative dental problem. There's an incredible excess of plaque formation and resulting calculus which never goes away even with proper cleaning treatment from a dentist. My teeth is constantly being eroded. This process has of course been gradual. I've been to many dentists and all of them have misdiagnosed me. I'm also producing a resulting odorous coating on my tongue which never goes away, even after trying out a oxygen rich dental product. Even the plaque i remove with floss is really odorous. I've also noticed white spots on certain areas of my teeth which i never had before. Of course now the formation of calculus has led to decay and parts of my teeth are being eroded. I also produce cotton mouth each and every time after brushing. I am completely lost. If anybody has even the slightest clue as to what's happening to me i would greatly appreciate some help!
